The Athletics called up their top prospect on Saturday, inserting shortstop Franklin Barreto into the lineup for their second game against the White Sox. Barreto was originally scheduled to make his major league debut on Sunday, but got a head start after Jed Lowrie sustained a minor knee sprain in Friday’s 3-0 win and was scratched from Saturday’s lineup.

Barreto, 21, has been rapidly climbing the rungs of the A’s minor league system after getting dealt by the Blue Jays in 2014. He got his first taste of Triple-A action late last year, going 6-for-17 with three RBI and getting caught stealing in two attempts. He fared little better this spring, slashing .281/.326/.428 with eight home runs and a .754 OPS through his first 309 PA in Nashville.

While his minor league production has been solid, if underwhelming for a prospect of his caliber, the A’s are expected to give the rookie infielder a long leash with both Marcus Semien and Chad Pinder sitting on the disabled list. Pinder landed on the 10-day DL after suffering a left hamstring strain on Friday. Semien, meanwhile, is still working his way back from the 60-day DL with a right wrist fracture and likely won’t rejoin the team until he completes a rehab assignment with High-A Stockton.

Ken Rosenthal of The Athletic reports that the Angels will acquire second baseman Ian Kinsler from the Tigers. It is not known yet what the Tigers will receive in return. Kinsler had to waive his no-trade clause in order for the deal to happen.

Kinsler, 35, hit .236/.313/.412 with 22 home runs, 52 RBI, 90 runs scored, and 14 stolen bases in 613 plate appearances for the Tigers this past season. He’s in the final year of his contract and will earn $10 million for the 2018 season.

The Angels were certainly looking to upgrade at second base and did so with Kinsler. They were also reportedly interested in Cesar Hernandez of the Phillies.
